To wZZ whom it may concern: 4

Be it known that we, WILLIAM HENRY MEL- VIN, residing at Westminster, inthe county of Middlesex, and ANDREW MANN, residing at Oroydon, in thecounty of Surrey, England, subjects of the King of GreatBritain andIreland, have invented certain new and useful Improvements in Apparatusfor Collecting Mud, Dust, or other Street Refuse; and we do herebydeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same, reference being had to theaccompanying drawings, and to letters and figures-of reference markedthereon, which form a part of this description.

This invention relates to apparatus for 001- lecting mud, dust, andother street refuse and for transferring such refuse to a van or cart.

Figure l of the drawings represents in elevation the right-hand side ofthe apparatus.

Fig. 2 is a plan View, partly in section,of the lower part of theapparatus. Fig. 3 is an elevation of the left-hand side of theapparatus. Fig. 4 is a front elevation. Fig. 5 is a verticallongitudinal section of the collecting trough and apron, and Fig. 6 is aplan view of the under side'of these parts.

A suitable box-like frame ais provided with inspect-ion lids or coversI) c, mounted on two large road-wheels d and,if desired, also'on a smallwheel e in a swiveling fore-carriage f, which may be connected to a dustvan or cart, (not shown,) the whole being propelled by horse or motorpower. The apparatus is provided, as best seen in Figs. 1, 5, and 6,with an inclined apron constructed of two parallel sections g and h. Thesection 9 is rigidly mounted 'in the frame a, while the section It ismounted on,*and slidably connected to, the rigid section by means ofguidepins 52, which aresecured at one end to lugs 54:, mounted onthe-under side of section h, and headed pins 56. The other ends of thepins pass through and. have bearing in lugs 53, mounted on the underside of section g, and a coiledspring 41 is mounted on each pin betweenthe two lugs and by hearing against both lugs tend to keep them apartand the apron extended. Guide-slots 55 are formed frame a.

in the movable section It, and headed pins '56 on the stationary sectionpass through the slots and limit the sliding movement of said movablesection. By thus making the apron in two sections and connecting them asdo scribed a resiliency is given to the frontsection which permits it togive when an obstacle is encountered, thus lessening the 'liability ofbreaking the machine. The front section is also provided with roundedcorners, as shown in Fig. 6, to decrease the liability of its catchingon tram-lines or other obstacles. Normally when working the slidingapron h is just touching the ground and receives the mud or refuse whichis thrown thereon by a cylindrical brush it. This brush is rapidlyrotated indirectly 'by one of the road-wheels by means of asprocket-wheel l, loosely mounted on the axle d and caused to turn, withthe wheel, by pinconnections 59. A chain m, traveling over saidsprocket-wheel Z, imparts motion to a sprocket 71, mounted on a stud 0on a frame p, that is secured to the A second sprocket g, which turnswith the sprocket n, imparts motion, through the medium of a chain 1",to a sprocket s on a stud t, fixed to the lower part of said frame a,

and with the sprocket 8 another sprocket u,

mounted on the same stud, is caused to turn and communicates motionthrough the medium of a chain '0 to a sprocket'w on the shaft of thebrush it.

The apron or the movable part hthereof is connected by links m to a handlever or levers y, pivoted to the framea, for the purpose of withdrawingthe section It back onto the stationary section 9 away from the groundwhen the apparatus is traveling but not collecting refuse. In order thatthe dirt or refuse thrown up by the brush konto the apron may travel upthe same and into a horizontal trough 2, (best shown in Figs. 2 and 5,)we provide a number of squeegees l, which pass along in contact with theface. of the apron. These squeegees are mounted on endless chains 2,which pass around sprockets 3, 4:, and 5, said sprockets being mountedon spindles, having bearings in each side of the frame a. The spindle 6,on which the sprocket 3 is mounted, has on the left-hand side of themachine outside of the frame a,

Fig. 3, a sprocket 7, and this sprocket receives motion by means of achain 8 and a sprocket 9, also mounted on the axle of the road-wheelsand adapted to receive motion from the left-hand wheel by the pinconnections 59, or said sprocket 9 may be made integral with the wheel.

The bearings 10 of the brush are adjustable as to height to allow forwear of the brush or otherwise. A suitable way of eifecting thisadjustment at both ends at once is to suspend the bearings on screws 11,having miter-wheels 12 fixed thereto and which gear with miter-wheels13, mounted at each end of a horizontal shaft 14, said shaft having ahand-wheel 15 or the like to actuate it.

The shaft 6 has also mounted thereon a gear-wheel 16, Fig. 2, whichgears with a wheel 17, fixed on a shaft 18 of a horizontal screwconveyer 19, which has bearings at each end and worksin halfof thehorizontal trough z and conveys all the refuse contained'in said half tothe middle of the trough. The other half of the trough contains asimilar screw conveyer 20, which conveys all the refuse contained inthis half to the middle of the same, and motion to this last conveyor isobtained by a chain 21 from a third sprocket 22, mounted on the stud 0on the frame 10, before referred to, (see Figs. 1 and 4,) to asprocket-wheel 23 on the shaft of the conveyer 20. Bearing-blocks 57 areprovided in the trough for the inner ends of the horizontalconveyer-shafts.

The object in bringing the refuse to the middle of the horizontal troughis to prevent the said refuse from clogging at the delivery end, as itis liable to do if only one horizontal conveyer be employed.

In order to raise the refuse from the middle of the trough so as to beable to deliver it over the tail-board of a van or the like, we providea vertical conveyer-tube 24:, in which is mounted a screw conveyer 24.,on the end of which latter is a bevel-gear 27, in mesh with a bevel-gear26 on a horizontal counter-shaft 25, mounted at the top of and acrossthe frame 29. This shaft 25 is rotated by means of a sprocket-wheel 33,mounted on one end thereof, said sprocket receiving motion through themedium of a chain 28,driven bya sprocketwheel 29 on the axle of theroad-wheels.

At the junction of the vertical and horizontal conveyors we provide amanhole 30, Figs. 1- and 3, for the purpose of inspection, adjustment,and so on, and there is fixed a hinged spout 32, near the top of thevertical conveyer, for directing the refuse over the tail-board into thevan or cart.

A suitable clutch 34, having an operating lever 35, Fig. 4:, is providedto disconnect the counter-shaft when the apparatus is traveling, but nototherwise operatin Nuts 41 and 45 may be employed to secure the spindlesof sprockets 4 and 5 in their adjnsted positions in the bearing-slots inthe casing. To adjust the sprocket 5 nearer to the broom, loosen thenuts, lower the spindle 4, and tighten the nut when in the desiredposition, then adjust the sprocket 5 nearer to the broom and tighten itsnut. Wherever necessary, we provide jockey pulleys or rollers onadjustable studs to take up the slack of a chain, such as thejockey-pulley 31, bearing on the chain 28.

What we claim is- 1. An apparatus for collecting street refuse,comprising a suitable framing, a brush, a collecting-trough, areceiving-apron comprising a fixed section,and a movable sectionslidably connected to said fixed section and arranged to receive refuseswept thereon, an endless conveyer to move the refuse from the aproninto said trough and means for conveying. the refuse away from thetrough, substantially as described.

2. In an apparatus for collecting street refuse, the combination with asuitable framing, a brush at one end, and a collecting-trough at theopposite end of said framing, a receivingapron comprising a fixedsection, and a movable section slidably connected to said fixed section,means for normally holding the movable section in contact with the road,means for withdrawing said latter section from the road and a conveyerto move the refuse from the apron, of an upright conveyer adapted toreceive the refuse from the trough, substantially as described.

3. In an apparatus for collecting street refuse, the combination with asuitable framing, a brush at one end and a collecting-trough at theopposite end of said framing, a receivingapron comprising a fixedsection, and a movable section slidably connected to said fixedsection,springs for normally holding the movable section in contact withthe road, levers connected to said movable section for sliding it backonto the fixed section, and an endless conveyer adapted to move over theapron and remove the refuse therefrom, of an upright conveyer adapted toreceive the refuse from the trough, substantially as described.

In testimony whereof we have signed our names to this specification inthe presence of two subscribing witnesses.
